Thanks Ben. I could use that code but it might need a small variation. I only need one specific side or edge of the 2-D domain and the code gives me the whole of the boundary mesh. While this is useful for other purposes, this is very confusing when I try to read it back in as a 1-Dimensional mesh.
Now that I think about it, I guess I could have just looped through the 2-D mesh and then extracted nodes that fall on a certain side. This could be done now a lot easily once I have obtained the boundary mesh using meshtool.cc also. Well, thanks for pointing out the meshtool app to help me out ! ~Vijay On Wed, Nov 19, 2008 at 11:33 AM, Benjamin Kirk <[EMAIL PROTECTED]> wrote: > > Take a look at 'src/apps/mesh_tool.cc' - > > The '-b' command-line option should do exactly what you want. > > You can either try using meshtool or extract the relevant code for yourself. > > -Ben > > > On 11/19/08 9:17 AM, "Vijay S.
